Overview of REXX sample programs

The sample programs and the jobs that you can use to run them are located in the SEZAINST file.

The following information applies to the batch jobs:

The batch job REXXAPI runs standalone socket EXECs and TCP/IP clients.
The batch job REXXAPIS runs TCP/IP servers.
The batch job REXXAPIT runs the subtask that is required to test the REXAPI04 program.
